Heavy-Duty Poly Tees – Professional 3-Way Irrigation Branch Connectors (Bag of 20)

Heavy-Duty Poly Tees – Professional 3-Way Irrigation Branch Connectors (Bag of 20)

Efficient nutrient distribution relies on a well-structured plumbing network that can branch and divert flow without losing vital head pressure. Our Heavy-Duty Poly Tees are the industry-standard solution for splitting a single irrigation line into two or adding a secondary pipeline to an existing run. Specifically engineered for Low-Density Poly (LDPE) and Drip Tube, these fittings provide a robust, leak-proof junction that stands up to the high-frequency cycles of automated hydroponic systems. Trusted by professional installers for their durability and consistent fit, these tees ensure your main supply "spine" can effectively feed multiple zones, trays, or rows with total reliability.

Best For: Branching main supply lines into multiple grow zones, creating manifold "T" junctions, and expanding existing irrigation layouts with additional pipelines.

Key Features

• High-Tensile Barbed Grip: Features precision-moulded, aggressive barbs on all three outlets that bite deeply into the poly pipe, ensuring a secure, pull-out resistant connection that remains watertight under pressure.
• Industrial UV-Stabilisation: Manufactured from premium-grade polymers designed to withstand the intense radiation of Australian sun and indoor HID/LED grow lights without becoming brittle or cracking.
• Max-Flow Internal Bore: The internal path is designed to minimise turbulence and pressure drop at the junction, ensuring consistent nutrient delivery even to the furthest plant sites in your system.
• Chemical & Salt Resistant: Built to handle continuous exposure to concentrated mineral salts, organic nutrients, and pH adjusters common in hydroponic reservoirs without degrading or leaching.
• Installation-Grade Reliability: These are the same high-quality fittings used by professional irrigation specialists, chosen for their long-term performance in both commercial and hobbyist environments.
• Opaque Algae Prevention: The deep black pigmentation ensures total light blockage, preventing algae from colonising the fitting and protecting your downstream emitters from organic blockages.

Available Sizes

• 13mm Poly Tee (Bag of 20): The standard size for secondary distribution lines and smaller hobbyist irrigation setups.
• 19mm Poly Tee (Bag of 20): The versatile "all-rounder" for medium-flow distribution lines and grow room manifold branching.
• 25mm Poly Tee (Bag of 20): The professional choice for high-volume main supply lines and large-scale commercial irrigation networks.

Specifications

• Material: High-Impact Polypropylene / ABS
• Fitting Type: 3-Way Barbed Compression
• Compatibility: Low-Density Poly Pipe (LDPE) and Drip Tube
• Quantity: 20 Pieces per Bag
• Colour: Black (Light-Proof)

Installation & Maintenance Tips

• Thermal Seating: For the easiest installation and the tightest seal, dip the ends of the poly pipe in a cup of hot water for 15 seconds to soften it. This allows the tee to slide on fully and "shrink-wrap" around the barbs as it cools.
• Balanced Layout: When splitting a line to feed two identical trays, try to keep the pipe lengths on either side of the tee roughly equal. This helps maintain balanced pressure and flow rates across both zones.
• Square Cuts: Always use a sharp pipe cutter to ensure perfectly square cuts. This allows the pipe to seat fully against the internal shoulders of the tee, ensuring maximum surface area for the barbs to grip.

Ideal For (Uses)

• Manifold Construction: Building professional-looking "T" junctions to distribute water from a central pump to multiple grow tables or reservoir systems.
• System Expansion: Easily tapping into an existing 19mm or 25mm run to add a new irrigation zone or extra pots without redesigning the entire layout.
• Agricultural Irrigation: Durable enough for use in greenhouse and outdoor garden beds where reliable 3-way branching is required.
